CVE-2004-2760

Severity: medium (CVSS 6.8 v2.0)
Exploited in the wild: not listed in CISA KEV
EPSS: 8.7% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2004-12-31 · updated 2026-06-16
Weakness: CWE-16

Description

sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.

Affected products

OpenSSH: 3.5, 3.5p1
